DID I JUST BLEW A HEAD GASKET?

[D180SX760]

I drove the car for like 2 hours. the car had oil and water before i drove it. And i decided to see what my top speed was with the new ka24de we swap in. well it topped i guess beyond 120. i never noticed any overheating. i decided to stop at some gas station. After i turned the car off i couldnt get em to start. so finally a while after the car cooled down i put some water. The car started and it ran for a lil while but i decided to stop again and i cheked the oil and the oil started to look like chocolate, the water got into the oil i guess. so u guys think That i blew my piston rings and head gasket???? what can i do to fix the problem so it wont happen again

If there's oil on the tips of any of your spark plugs, it usually means that you're getting pretty bad blowby or one of your rings is gone.

A ring going out wouldn't cause oil to mix in with the coolant though.

Do a compression test on all cylinders to determine if you've got a blown head gasket. You might also follow that up with a leak down test to determine if you got bad rings.

If you have to replace the head gasket, make sure the head surface is not warped beyond 0.1 mm (0.004 in).

When torquing down the head, follow the procedure as outlined in the FSM.
